Just bought the AD&D L1 module and I'm disappointed to see the scan was made of an original with pencil marks. Very poor quality compared to the other stuff I've purchased. I'd really like to see you acquire a higher quality source and replace this version with something better.

It is true that the scan is poor. The papers that were scanned obviously were used by a Dungeon Master at some point because one can see the faded pencil marks where monster hp counts were crossed out. That said, the adventure is a fun one and -- as I am doing at this point -- converting it for 5th Edition use is easy as pie.

A great adventure but a flawed PDF.
L1 is a fantastic module, great fun for a low level party and very easy to use for the DM. The detail used to describe Restenford makes it an ideal base of operations for the party. The rulers, notable NPCs, and even guards and shopkeepers are given short stat blocks. The eponymous ruins on Bone Hill are also well written and well thought out. A little tough for a low level party, but exciting and interesting.
However, the PDF conversion was poorly done. First thing you notice is that all the pages are crooked. Next, the OCR is incomplete. It was only partially successful, so many words are lumped into groups when selected. And lastly, there are pencil marks in the module; dashes and what appear to be decreasing hit point counts (it looks like the original owner's party attacked some of the townsfolk :). I really expected more from Wizards of the Coast. If you are out there reading this WotC, please fix it. This module was a gem in the crown of TSR, please do it justice.
